This image shows a slit lamp retro-illumination photograph through dilated pupil revealing silicone oil in anterior chamber following retinal re-attachment surgery. Silicone oil is a commonly used approach for retinal tamponade during surgery in the vitreous or for retinal reattachment surgery. While the silicone does assist with successful reattachment, often it causes optical complications resulting in followup surgeries to remove the silicone oil typically 2-8 months later. Gas bubbles with SF6 or C3F8 are also used, with the advantage that there is no myopic shift post operation and no followup surgery is required.

This image was taken by Paula Morris of the Moran Eye Center using a Zeiss photo slitlamp and a Nikon D-1S camera at and 24x magnification. Notably, this image won Honorable mention in the Photo Slit Lamp Biomigraography Division in 2007.

Grand Rounds for today is an interesting finding of an anomalous congenital blood vessel that crosses the front of a pupil, relaxing when the pupil is small, and pulling taut when the pupil becomes is dilated. The image above is relaxed with a small pupil.

Venous phase fluorescein sodium angiogram of a dark choroid in Stargardt’s disease or fundus flavimaculatus.
